Answer:
l = 6 cm
Step-by-step explanation:
l = x
b = 8 cm
Perimeter = 2(l+b)
Perimeter = 28 cm
28 = 2(l+b)
l+b = 14
l + 8 = 14
l = 14 - 8
l = 6cm

Step-by-step explanation:
- Here, Breadth = 8 cm
- And perimeter = 28 cm
- So, perimeter of rectangle = 2(l+b)
- 28 = 2(l+8 ) => 28/2 = l+8 => 14 = l+8
- Length = 14-8 = 6 cm
